Migrating a Replicated Site

4.
Retire the 4.x supplier.
The Directory Server 6.x that you configured in Step 1 is now the only supplier
in the topology.
Example: Detail of Steps
Consider a fairly simple replication topology:
• One supplier Server A
• Two consumer servers Server B and Server C
• Server A has a supplier-initiated replication agreement to Server B and to
Server C
• Servers A, B, and C are 4.0, 4.1, 4.11, 4.12, or 4.13 Directory Servers.
To migrate this topology, follow these steps:
1.
Install Directory Server 6.x on a new server, Server D.
2.
Configure Server D for the role it will fulfill in the migrated replication
topology, that is as a read-write replica that logs changes.
This procedure is explained in the Replication chapter in the Netscape Directory
Server Administrator’s Guide.
3.
Then configure Server D to be a legacy consumer.
This procedure is explained in the Replication chapter in the Netscape Directory
Server Administrator’s Guide.
4.
Upgrade Server B to Directory Server 6.x, following the instructions given in
the Netscape Directory Server Installation Guide.
5.
Make Server B a read-only replica of Server D.
This means that Server D is now a hub supplier: it receives updates from
Server A, and in turn updates Server B.
NOTE You can migrate a topology where Server B and Server C have CIR
replication agreements with Server A. However, you cannot have
CIR agreements in the new replication environment because
Directory Server 6.x does not support consumer-initiated
replication.
